Collagen Glow Booster Serum radiance-enhancing and firming booster serum with collagen

💗 Collagen Glow Booster Serum – a milky glow booster for plump, elastic and radiant skin

The medicube Collagen Glow Booster Serum is a concentrated, milky booster serum developed to support a fuller, smoother and more radiant appearance of dull, drier, and less elastic skin.

The formula’s speciality lies in combining hydrolysed collagen and elastin with proteoglycan, 1% milk protein extract, PDRN, niacinamide and Hexapeptide-2. It also contains ceramide NP, beta-glucan, a hyaluronic acid derivative and adenosine, so the serum not only adds radiance to the skin: it builds a more hydrated, plumper and more elastic skin texture.

Its silky, milky texture spreads easily and targets that soft, “glazed”, pearlescent glow that comes not from shine but from a well-hydrated, smooth skin surface.

✨ What does it do?

• Immediately provides a plumper, more hydrated skin feel: glycerin, milk protein extract, hyaluronic acid derivative and other moisturising ingredients help replenish moisture in the skin.
• Supports a firmer, more elastic skin texture: hydrolysed collagen, hydrolysed elastin and proteoglycan complement each other to help achieve a smoother, plumper appearance.
• Makes dull skin more radiant: niacinamide and Hexapeptide-2 support a more even, fresher tone.
• Contains PDRN: an ingredient listed as Sodium DNA in the INCI, part of the moisturising and barrier-supporting formula.
• Supports the skin barrier: ceramide NP, hydrogenated lecithin, beta-glucan and niacinamide help maintain skin comfort and hydration.
• Helps refine lines emphasised by dehydration: a more hydrated, plumper skin surface appears smoother and more even.
• Provides a striking glow finish: the milky formula leaves a soft, hydrated, “glazed skin” appearance.

🧬 Key active ingredients

Hydrolysed collagen + hydrolysed elastin

Two skin-conditioning and moisturising protein-derived ingredients that help make the skin surface feel softer, smoother and more elastic.

The current European product communication related to the product highlights 260 Dalton molecular weight, ultra-low molecular weight collagen. The small molecular size is a key element of the formula’s light, fast-absorbing character.

1% milk protein extract

The formula contains 10,000 ppm, i.e. 1% Milk Protein Extract. Milk protein provides amino acids and other skin-conditioning components that help maintain a more hydrated, softer and more elastic skin feel.

PDRN – Sodium DNA

Medicube highlights PDRN alongside milk protein extract in the formula. This ingredient appears as Sodium DNA in the INCI list and relates to the product’s moisturising, barrier-supporting concept.

Soluble Proteoglycan

Proteoglycans are components associated with structures present in the skin’s natural extracellular matrix. In cosmetic formulas, they are used for their water-binding and skin-conditioning properties, helping to create a plumper, more elastic and smoother skin feel.

Niacinamide

A versatile form of vitamin B3. It supports the skin barrier and hydration while helping to create a more even, clearer and radiant skin appearance.

Hexapeptide-2 + glucose

The formula contains Hexapeptide-2 and glucose. Medicube primarily associates this combination with supporting a more even, radiant skin tone.

Ceramide NP + beta-glucan

Ceramide supports the skin’s natural lipid barrier and helps reduce moisture loss, while beta-glucan acts as a moisturising and skin-conditioning ingredient to support a more comfortable skin feel.

Hydroxypropyltrimonium Hyaluronate

A modified form of hyaluronic acid that adheres well to the skin surface and helps maintain its hydration and softness.

Adenosine

An ingredient frequently used in Korean skincare that fits well with the formula’s concept targeting smoother, more elastic skin texture.

🎯 Who is it recommended for?

The Collagen Glow Booster Serum may be a particularly good choice if:

• Your skin looks dull or tired,
• Your skin is dry or dehydrated,
• You want a plumper, more elastic skin texture,
• Fine lines appear more pronounced due to lack of hydration,
• Your skin has lost its natural radiance,
• You like light but nourishing milky serums,
• You want a “glass skin” or “glazed skin” effect,
• You are looking for a concentrated booster to add to your usual serum or moisturiser.

Medicube recommends it for all skin types, including dry, normal, combination, oily and sensitive skin.

🥛 Texture and place in the routine

Silky, milky booster texture that is creamier than watery serums yet not heavy. Leaves a hydrated, soft and gently luminous skin surface.

The special airless packaging has a mechanism at the bottom that must first be turned to open, then the serum can be dispensed by pressing the pump.

Can be used morning and evening:

1. After cleansing and toning, open the dispenser.
2. Medicube recommends 2–4 pumps per use.
3. Gently pat the serum into the skin of the face, neck and décolletage.
4. Follow with moisturiser.
5. After use, turn the mechanism back to the closed position.

Extra glow tip: according to medicube, you can mix one pump with another serum or moisturiser for an even more radiant, hydrated finish.

💗 Why do we love it?

Because this is not just a smaller version of the Triple Collagen Serum.

The Collagen Glow Booster is much more a concentrated glow and plumping booster: it combines collagen and elastin with proteoglycan, milk protein, PDRN, niacinamide, peptide, ceramide and moisturising ingredients.

The milky texture is also special in itself: a small amount gives a soft, smooth, plump and luminous skin surface, so it works well even if you don’t want to add a full new serum step to your routine, just a little extra hydration and radiance.

And that’s the good part: in 15 ml you don’t get just another general collagen serum, but a targeted small glow booster that can be used alone, layered or even mixed with moisturiser.

❓ Q&A

What is the difference between Collagen Glow Booster Serum and Triple Collagen Serum?

The Triple Collagen Serum is a more classic, full-face hydrating collagen serum primarily supporting hydration, elasticity and plumper skin texture.

The Collagen Glow Booster Serum is a more concentrated booster and contains milk protein extract, PDRN, proteoglycan and Hexapeptide-2 alongside the collagen–elastin system. It focuses especially on a radiant, plump, “glazed skin” finish.

Why only 15 ml?

This product is not designed as a traditional large-size serum but as a concentrated booster step. A few pumps per application are sufficient, and it can be mixed with other serums or moisturisers.

Can I use it alongside other serums?

Yes. You can use it as a standalone serum or after/combined with another serum. Medicube specifically recommends mixing one pump with moisturiser or another serum for an extra hydrated, radiant finish.

Can it be used in the morning before makeup?

Yes. Its silky, milky texture and radiant finish make it especially suitable for the morning routine. Allow it to absorb, then follow with moisturiser and sunscreen.

Does it contain PDRN?

Yes. Medicube highlights PDRN in the formula; you will find the ingredient listed as Sodium DNA in the ingredient list.
